PORTABLE MOVING-PICTURE MACHINE.

Specification of Letters Patent.

Patented Oct. 8, 1918.

To all whom it may concern:

Be it known that I, FREDERICK C. TAY- LOR, a citizen of the UnitedStates, residing at the city of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Portable Moving- Picture Machines, of whichthefollowing is a specification.

My invention relates in a moving picture machine to a circuit breaker toautomatically cut out the motor and shut off the illumination of themachine for repairing broken film.

The nature and scope of my invention will be better understood from thefollowing description taken in connection with the accompanying drawingsforming part hereof, in which Figure 1, is a side elevational view ofthe portable fire-proof cabinet in an open position, showing internalmechanical and elec trical equipment, in a preferred form, and thecircuit breaker of my resent invention in application and in whic thefilm traveling in contact therewith through the machine in case ofbreaking of such film of instantly the motor being stopped and the lampextinguished; and

Fig. 2, is an enlarged view, partly in central longitudinal section andartly in elevation, of said circuit breaker evice.

Referring .to the drawings a, is a rectangular-shaped asbestos or otherfire-proof material cabinet or holder for the followinginstrumentalities :-A feed reel 5, is operated by an electric motor 9,located in one corner of the cabinet, as shown in Fig. 1, and which willbe presently more fully described. Beneath the take-up reel 6 isarranged a sprocket-wheel b Alongside this wheel and in a positionadjacent thereto is arranged a friction guide-roll 5 The sprocket-wheelb and the roll 6 are supported in position above the projector-lens 0,extending from the housing 0 in which is preferably mounted a pivotedintermittently operating sprocket c and supported from said housing arerespectively, a friction guide-roll 0 and opposite the same is arrangeda. sprocket 0, both supported from the housing. A lamp-house d, ispreferably located centrally of the cabinet a, in rear of theaperture-plate 0 carried by the projector-lens housing 0 The lamphouse(I, is provided with an incandescent or other type of electric lamp (1.arranged in the circuits 10 and 11, looped into the main line circuits12-13 from a source of energy. not shown, and in which circuits theelectric motor 1. is included. The lamphouse (I, is provided withcondensing lenses (Z Below the lan'ip-house (Z. as shown in Fig. 1.considered with respect to one corher of the said house (I. is located aguide roll 0. Above the lamp-house (Z. and at the left hand corner ofthe cabinet a, is located the said take-up reel 5-".

The circuit breaker ll, of my invention comprises a housing [1. the roofwhereof. is provided with guide-rolls 72 and k arranged at differentelevations with respect to each other. The housing k carries aswinging-arm it, having a weighted roll it. at the free extremitythereof and which roll as well as the guide rolls b and b is normally inbearing contact with the traveling film 2', as clearly shown in Fig. Inthe housing iii. are provided binding posts it and It. in engagementwith the insulating base of the housing If, and re movably securedthereto. The line wires 14. and 15 from the source of energv and inwhich the motor 9, and are or incandescent lamps (l of the machine areincluded. are connected with the posts it and h'". respectively. Theseposts are perforated about midway in their length, as clearly shown inFig. 2 and through which a longitudinal circuit breaking rod If, isafforded play therein. The rod it is provided with a shoulder h and acollar iv and it carries thereon an insulating sleeve 11 A leaf springit, projects vertically from the binding post it", and surrounds theinsulating sleeve it. and bears normally against the collar 7L9. whenthe rod 72 is held in a slantinglv in clined position under thecompression of the coiled spring it, carried on the lower end of rod71-8 by the engagement of the shoulder 71 with the binding post 11. Thisspring is in bearing contact at one end against the support h. and atthe opposite end against the cap it. romovablv secured to the lowerextremity of said rod it lvhen a film ibreaks. the weighted swinging-arm7:. falls contacting with the rod k which owing to its weight depressesthe rod, thereby disengaging its shoulder h from the binding post h,when the sprmg It will move the said rod to the left, as shown in dottedlines in Fig. 2. This movement of the rod h disengages its collar h fromthe leaf spring h lVhen the rod it occupies the middle position in theopenin s of the binding posts It and h, the circuits lat and 15, arebroken and thereby the motor g, stopped and the lamp d cut out of thesaid circuits. This condition thus permits an attendant to readilyrepair the broken film in order to again be able to quickly manipulatethe machine for its designed purpose, after restoring the weightedswinging-arm h, to the position it previously occupied, as illustrated,for example, in Fig. 2, in engaging contact with the uper surface of thefilm i, and with the rolls 2 and it respectively, in bearing contactwith the under surface thereof.

The foregoing instrumentalities and their arrangement having beendefined and described, I will now proceed to explain briefly thecoursing of the non-intla1nmable or other type of film 2', from the feedreel 12, downward in a taut straight vertical inclined course around theguide roll a, then between the. switching device IL, around the sprocketc, and between it and the guide-roll 0 then between the guide-roll 0,and sprocket c and fed verti ally in front of the apertureplate 0 into aloop between the guide roll 2 and around the sprocket b and thencevertically to the take-up reel 5 whereon the non-inflammable or othertype of film 2',

is wound for use again or removal from the same.

Between the respective reels 1) and b the cut-out switching device 71.,automatically acts in case of the breaking down of the film 2', in itscoursing to instantly stop the motor and cut oil the illumination of themachine in the manner hereinbefore explained as well as feed of thefilm, until the same is repaired.

The defined coursing of the said film is automatic from the feed reel1), through the machine to the take-up reel 12 This is particularlydesirable as such type of portable machine is generally operated byinexperienced persons so that in case of the breaking or tearing of thefilm it can be instantly repaired with the least time, trouble orexpense attending the work.

Having thus described the nature and objects of my invention what Iclaim as new and desire to secure by Letters Patent is 1. A circuitbreaker device having a base with perforated posts supported therefrom,certain of said posts constituting terminals for an electric circuit,one of said terminals provided with a leaf-spring, a rod arranged in theperforation of said posts and having means normally engaging one of saidposts and carrying a spring normally held under compression, said rodhaving an insulating sleeve and metal collar. the latter normallycontacting with said leaf-spring, a weighted movable arm normally inengaging contact with a traveling film and means in engaging contact andalong which is guided said film, said weighted arm being adapted whenthe film breaks to drop, depressing said rod to release said spring andto disengage the collar from said leaf-spring. substantially as and forthe purposes described.

2. In a circuit breaker device. an insulating base, three perforatedposts supported thereon, two of which posts constitute terminals for anelectric circuit, one of said terminals being provided with a leafspring, a rod engaging said supports and passing through theperforations thereof, said rod having a shoulder normally engaging oneof said posts and carrying a spring normally held under compression,said rod also having an insulating sleeve and metal collar. the latternormally contacting with said leaf-spring, and a weighted swinging-armnormally in engagingcontact with a traveling film and rolls in engagingcontact and along which said film is guided, said weighted arm beingadapted when the film breaks to drop, depressing said rod to releasesaid spring and to disengage the said collar from the said leaf-spring,substantially as and for the purpose described.

In witness whereof I have hereunto set my signature in the presence ofthe two subscribing witnesses.
